Process for foliar fungicide treatment and fungicide composition for implementing the process

Abstract

The present invention relates to a process for the control of fungal disease of plants by applying to the leaves of the plants: a) 2-(4-chlorobenzylidene)-5,5-diemethyl-1-(1H-1,2,4-triazol-1-ylmethyl)- 1-cyclopentanol; b) one or more fungicides suitable for protecting against the said fungal diseases and to compositions which may be used in the process.

We claim: 
     
       1. A process for the treatment of a plant suffering from, or protection of a plant subject to, fungal diseases which comprises applying to the leaves of the plant a fungicidal and non-phytotoxic amount of a component (a) 2-(4-chlorobenzylidene)-5,5-dimethyl-1-(1H-1,2,4-triazol-1-ylmethyl)-1-cyclopentanol and a component (b) at least one dithiocarbamic acid derivative fungicide, wherein the proportion by weight of component (a) to component (b) is from 0.0003 to 3,000, inclusive. 
     
     
       2. A process for the treatment of a plant suffering from, or protection of a plant subject to, fungal diseases which comprises applying to the leaves of the plant a fungicidal and non-phytotoxic amount of a fungicidal composition comprising a component (a) 2-(4-chlorobenzylidene)-5,5-dimethyl-1-(1H-1,2,4-triazol-1-ylmethyl)-1-cyclopentanol, a component (b) at least one dithiocarbamic acid derivative fungicide and an agriculturally acceptable carrier, wherein the proportion by weight of component (a) to component (b) is from 0.0003 to 3,000, inclusive. 
     
     
       3. The process according to claim 1, wherein the fungal diseases are diseases of cereals, vines, market garden crops, arboricultural crops, tropical crops, rice, maize, beet or rape. 
     
     
       4. The process according to claim 2, wherein the fungal diseases are diseases of cereals, vines, market garden crops, arboricultural crops, tropical crops, rice, maize, beet or rape. 
     
     
       5. The process according to claim 1 wherein the dithiocarbamic acid derivative is selected from the group consisting of maneb, mancozeb and zineb.   
     
     
       6. The process according to claim 2, wherein the dithiocarbamic acid derivative is selected from the group consisting of maneb, mancozeb and zineb.   
     
     
       7. The process according to claim 1, wherein the proportion by weight is from 0.001 to 1,000, inclusive. 
     
     
       8. The process according to claim 2, wherein the proportion by weight is from 0.001 to 1,000, inclusive. 
     
     
       9. The process according to claim 1, wherein the amount of component (a) and component (b) applied is 0.002 to 1 kg/ha. 
     
     
       10. The process according to claim 2, wherein the amount of component (a) and component (b) applied is 0.002 to 1 kg/ha. 
     
     
       11. The process according to claim 9, wherein the amount applied is 10 to 600 g/ha. 
     
     
       12. The process according to claim 10, wherein the amount applied is 10 to 600 g/ha. 
     
     
       13. The process according to claim 2 wherein the fungicidal composition further comprises an agriculturally suitable surface-active agent. 
     
     
       14. The process according to claim 5, wherein the dithiocarbamic acid derivative is maneb. 
     
     
       15. The process according to claim 6, wherein the dithiocarbamic acid derivative is maneb. 
     
     
       16. A composition for the protection of a plant suffering from, or subject to, fungal diseases comprising a component (a) 2-(4-chlorobenzylidene)-5,5-dimethyl-1-(1H-1,2,4-triazol-1-ylmethyl)-1-cyclopentanol, a component (b) at least one dithiocarbamic acid derivative fungicide and an agriculturally suitable inert carrier, wherein the proportion by weight of component (a) to component (b) is from 0.0003 to 3,000, inclusive. 
     
     
       17. The composition according to claim 16, wherein the dithiocarbamic acid derivative is selected from the group consisting of maneb, mancozeb and zineb.   
     
     
       18. The composition according to claim 16, wherein the proportion by weight is from 0.001 to 1,000, inclusive. 
     
     
       19. The composition according to claim 17, wherein the dithiocarbamic acid derivative is maneb. 
     
     
       20. The composition according to claim 16 further comprising an agriculturally suitable surface-active agent.
